IMPROVEMENT IN DROPPERS FOR SEED-PLANTRS.

Specilication forming part of Letters Patent No. 145,575, dated December 16,1873; application filed September 13, 1573.

To all whom it may concern:

Be it known that I, HERMANN H. KOELLEE, of Camp Point, in the county of Adams and State of Illinois, have invented a new and useful Improvement in Dropper for Seed-Planters, of which the following is a specication:

Figure l is a top view of my improved dropper shown as applied to the seed box of a planter. Fig. 2 is the same view as Fig. 1, with the distributing and dropping plates removed. Fig. 3 is a detail vertical section of my improved dropper, taken through the line w w, Fig. 1. Fig. 41. is a bottom view of the same, partly in section, through the line y y, Fig. 3. Fig. 5 is a detail view of the dropperplate. Fig. 6 is a detail section of the cut-off, taken through the line z z, Fig. 1.

Similar letters of reference indicate corresponding parts.

Fig. 3, in the opposite sides or shoulders of which are formed slots to receive the v sliding bar O, by the movements of which the dropper is operated. To the center of the bottom B is attached, or upon it is formed, a projection, D, which passes up throughA a longitudinal slot in the sliding bar C, and through the center of the star-wheel E, to form a pivot for said wheel. The star-wheel E is secured upon the pivot D by a screw. The star-wheel E is made with seven rays or arms, thc outer ends of which are made more inclined upon one edge than the other, so that the point or extreme end of the arms may be at one side of the radius passing through the centers of the s-aid arms. To the upper side of the sliding bar O are attached, or upon it are formed, two wedgesliaped projections, F, of such a form as to lit into the space between the rays or arms of the star-wheel E, and at such a distance apart that, when one of the said blocks F may be in the space between two of the arms of the starwheel E, the other block may be out of the sweep of the said arms as the wheel E turns. rlhe point of the blocks F is made more inclined upon the side next the more inclined side of the ends of the arms of the wheel E, so that, as the sliding bar O moves back and forth, the blocks F will, alternately, strike an arm of the wheel E, and turn it through half the space of one arm. G is the dropping-plate, which is made in the form of a circle with its middle part cut away. In the inner edge of the plate G are formed four notches, g{, to receive four projections, e', formed upon four of the arms ofthe starwheel F, so that the dropping-plate may be carried around by and with thestarwheel E. In the dropping-plate G, near its outer edge, are formed fourteen holes, arranged in a circle and at equal distances apart, as shown in Figs. 1 and 5, which holes receive the seed from the hopper and carry it to the discharge-hole b throughthe bottom B, through which it falls into the guide-spout that conducts it to the ground. 'H is the guardplate, which fits into the lower part of hopper, and is made with a ring-slot directly over the circle of holes in the dropping-plate G. The parts of the guardplate H are connected by three arched arms, h1, and by the cut-off case h2, as shown in Figs. l and 3. The circular middle part of the plate H is made convex upon its upper side, 'so that the corn may readily pass to the holes of the dropping-plate G. I is the cut-olf plate, which is pivoted in and to the case h2, and is held down upon the drop-plate G by a spring, J, as shown in Fig. 6, so as to prevent the dropping-plate G from carrying out any more seed than enough to lill the dropping-holes; The guardplate H is secured to the bottom B by two or more crossheaded screws, K, which pass through short slots in the said plate H, and screw into the said bottom B. By this construction, by turning the cross-head of the screws into line with the slots of the plate H, the said plate H may be removed, allowing the droppingplate G to be ,removed and replaced with 011e having larger or smaller dropping-holes, according as more or less seed is required to be dropped for a hill. Upon the loWer side of the sliding bar C, at its edge, is formed a projection, L, which passes through and Works in a slot in the bottom B, and to the end of Which is pivoted the end of the liar M, the other end of which s pivoted to the upper end of the bar or plate N, Which is pivoted to the conductor-spout or other support, so as to detain the corn in the conductor-spout, and Which is operated at each movement of the sliding bar C to allow the corn to drop to the ground.

Having thus described my invention, I claim as newr and desire to secure by Letters Patentl. The combination of the sliding bar C, beveled or Wedge blocks F, the star-Wheel E e', and the perforated ring dropping-Wheel G, having notches g', as shown and described, for the purpose specified.

2. The combination of the pivoted bar or plate N, connecting-bar M, and projections L with the bar, arranged to reciprocate and operate the seed-delivery mechanism.
